Leisure boat

ABSTRACT

Sailing boat designed for one or two crew members who can be accommodated inside a two-seater hull or cockpit ( 1 ), with a continuous longitudinal seat ( 2 ) equipped with a pair of back rests ( 3  and  4 ), the hull ( 1 ) having mounted on its front end a nose-piece ( 7 ) of considerable length, which at its free front end houses an extractable telescopic mast ( 17 ) and a pair of foldable side arms ( 11 ) associated with respective floating runners ( 12 ), all of which in such a way that the arms ( 11 ) can be folded onto the nose-piece ( 7 ), in the same way as the mast ( 17 ), and this assembly can then be folded onto the upper base of the hull ( 1 ), in a position which occupies a minimum amount of space and in which the boat can be easily transported on a wheel or roller situated at the rear, in the center, with the aid of a front manual pulling handle.

PURPOSE OF THE INVENTION

The present invention relates to a leisure boat, defined as a small boat intended for one or two crew members and intended to be propelled by the wind, this is a sailboat.

The object of the invention is to provide a structure for a boat that folds away to drastically reduce its volume in the inoperative position, providing easy storage and transport out of the water.

BACKGROUND OF THE INVENTION

There are leisure boats of small size, provided and designed for a small number of crew, which are usually driven by an outboard motor with the obvious polluting effects.

Also are known small sailboats with the classic configuration of a mono hull. Even though they may be in small size, it is practically impossible to remove manually from the water, nor transport and store easily during periods of inactivity.

This means, in practice, that for the maintenance of these boats, despite their small size, is needed to be carried out at a port jetty or otherwise employ the use of cranes, as well as special vehicles for transport to the place of storage, with an obvius economic cost.

Among the boats are known there are foldable boats, small size boats, or expandible boats with the posibility of adding accessories. In this sense, Spanish utility model No. 200701791, refers to a “Two Floats Folding Boat, transportable over ground by wheels, coupled with various accessories and interchangeable accessories”, with the possibility of incorporating, for example, a slide or seat accessories, but very bulky, despite its pliability.

Also, Spanish utility model No. 9800712 for “Folding Boat”, has characteristics that allow for its storage and transport, but is designed primarily as a dinghy built on a ship.

It is also known a folding boat, such as described in Spanish Utility Model No. 266.512, characterized by consisting of two halves joined by hinges to both sides, located on the edges, which allows folding one over the other so that the boat could be transported on a small trailer.

Finally, the patent WO100330ES describes a demountable trimaran convertible in sailing catamaran and mono-hull with motor. The trimaran is achieved form the assembly of two boats; a sailing catamaran, with side runners, rudders and keels, and a mono-hull with motor.

The boat proposed in this invention improves and completes what is previously known, describing an original boat, with new features, achieving a significant reduction in the volume of the boat and the possibility to be easily transported out of water.

DESCRIPTION OF INVENTION

The leisure boat proposed by the invention resolves in a fully satisfactory way the afore mentioned problems previously exposed.

More specifically, this boat has a hull with two-seater hull or cockpit, preferably buoyancy compartments to ensure flotation against any problem that may arise in the port or starboard flotation compartments. The main hull has a locked down bow beam arm that extends to support the fold out on mountable arms that the out runner floation modules are attached to. The two out runner flotation modules, when in the fixed position, provide a solid stable boat in conjuction with the main hull.

It is also characterized because the mast foot mounting telescopic is located at the front end of the bow beam. Here the bayonet fixture for the mast foot is connected. The mast foot is constructed with a foldable nuckle to facilitate ease on attaching the mast in a horizontal position then elevate the mast with sail to its vertical position. The mast is in two pieces which makes transportation and storage easy. A camber inducer is used to connect the lower sail batten providing a flexible batten boom to orientate the position of the sail.

It is also characterized the out runner supporting arms are folded back on the bow beam with a pivot point placed at the front of the bow beam. The supporting arms are also folded in two with a pivot joint half way down the arms. The bow beam and folded supporting arms are then all folded back over the top of the main hull seating area to provide an extremely compact package ready for transportation or storage.

In keeping with the compact and ease of handling features of the invention provitions have been made to facilitate the movilization of the boat. The main hull has two built in sockets in the lower central hull area where wheels on stub shafts can be inserted. This allows the folded up package to be transported on the ground or rolled down the beach or ramp to launch the boat when it is folded out, rigged up and ready to sail.

Other characteristic is at the front of the hull there is the tension bar to be used to attache the hull to the bow beam. When the boat is folded up ready for transport this tension bar is used as a hand grip to manually pull the package along.

The invention is also characterized because support for the pilot is movable along the longitudinal axis of the capsule two-seater and in areas corresponding to the footrest, the pilot stears the boat using the rudder activated by foot pedals.

The resulting design achieved a boat that has the acceptable dimensions for a utility boat. A length that does not exceed three meters and mast hight that is preferably no more than two meters and sixty centimeters high preferably. The folded away package therefore drastically reduces the overall size making it an easy manually transportable leisure boat.
